What is the significance of the filing date in a Continued Prosecution Application (CPA)?

The filing date of a Continued Prosecution Application (CPA) is significant for several reasons. In the context of inventorship, the MPEP ¶ 2.33 mentions:

It is noted that [1] identified as a named inventor in the Continued Prosecution Application (CPA) filed under 37 CFR 1.53(d) on [2], but no request under 37 CFR 1.48, as is required, was filed to correct the inventorship.

The filing date [2] is important because:

• It establishes the effective date for the CPA.
• It determines the timeline for filing certain documents, such as inventor oaths or declarations.
• It affects the calculation of patent term adjustment.
• It’s used as a reference point for determining whether changes to inventorship were properly requested.

Always keep the CPA filing date in mind when managing patent application procedures and deadlines.
